Clinical Picture and Risk Factors for Severity of SARS-CoV-2 and Dengue Coinfection in Children: Experience From a Tertiary Hospital in Vietnam.

Introduction Dengue is an infectious disease that is a burden in Asia-Pacific and Latin America. The COVID-19 pandemic in dengue-endemic areas has caused a "double burden" because of the possibility of coinfection, especially in children who are vulnerable to both COVID-19 and dengue. This study aimed to describe the characteristics and identify risk factors for the severity of the coinfection in Vietnamese children.

Intracranial Hemorrhage From Cerebral Venous Thrombosis With Hypereosinophilia and Positive Dengue Serology in a Child: A Rare Case and Challenges in Management.

Hypereosinophilia is a rare condition, defined as a persistent elevation of absolute eosinophil count greater than 1.5x10/L and/or tissue eosinophilia. This condition can be caused by numerous different etiologies, both hematological (clonal) and non-hematological (reactive).

Risk factors for disease severity and mortality of children with Covid-19: A study at a Vietnamese Children's hospital.

Introduction: To find out risk factors for disease severity and mortality of pediatric COVID-19 in the fourth wave of COVID-19 in Vietnam.

Methods: This retrospective cohort study was performed at Children's Hospital 1 from July to December 2021. All children with COVID-19 confirmed by a positive Realtime RT-PCR SARS-CoV-2 result and treated at COVID-19 department for at least 72 h were included.

Ecdysis triggering hormone modulates molt behaviour in the redclaw crayfish Cherax quadricarinatus, providing a mechanistic evidence for conserved function in molt regulation across Pancrustacea.

Molting enables growth and development across ecdysozoa. The molting process is strictly controlled by hormones - ecdysteroids. Ecdysteroidogenesis occurs in theprothoracic glands and stimulated by prothoracicotropic hormone in insects, while it ensues in the Y-organ and regulated by the molt inhibiting hormone in crustaceans.

An efficient passive planar micromixer with ellipse-like micropillars for continuous mixing of human blood.

In this paper, a passive planar micromixer with ellipse-like micropillars is proposed to operate in the laminar flow regime for high mixing efficiency. With a splitting and recombination (SAR) concept, the diffusion distance of the fluids in a micromixer with ellipse-like micropillars was decreased. Thus, space usage for micromixer of an automatic sample collection system is also minimized.

Design and optimization of non-clogging counter-flow microconcentrator for enriching epidermoid cervical carcinoma cells.

Clogging failure is common for microfilters in living cells concentration; for instance, the CaSki Cell-lines (Epidermoid cervical carcinoma cells) utilizing the flat membrane structure. In order to avoid the clogging, counter-flow concentration units with turbine blade-like micropillar are proposed in microconcentrator design. Due to the unusual geometrical-profiles and extraordinary microfluidic performance, the cells blocking does not occur even at permeate entrances.
